Scanning and tunneling electron microscopes are used to measure high resolution scientific images. As a general rule, the wavelength of the electrons must be at least as small as the item being scanned in order to detect/image the presence of the item. The new novel coronavirus has a size of 60 nm to 140 nm. The crowns or "corona" which are the protien like structures that extend from the body of the virus and have a length of 7 nm to 10 nm. The image above was taken at Rocky Mountain Laboratories in Montana, USA, using a tunneling electron microscope (TEM). What approximate size of wavelength was used to produce the image? 160 nm O 80 nm O 20 nm O 5 nm оооо
Light with wavelength ? = 635 nm is incident on a metallic surface. Electrons are ejected from the surface. The maximum speed of these electrons is v = 4.40 ✕ 105 m/s. a) What is the work function of the metal (in eV)? b) What is the cutoff frequency for this metal (in Hz)?
Barium has a work function of 2.48 eV. What is the maximum kinetic energy of electrons if the metal is illuminated by UV light of wavelength 375 nm? What is their speed?
